The Yudu adult t-shirt platen comes with an adhesive sheet already in place, covered with a piece of film so things don't stick to it until you are ready. While not a very strong adhesive, it holds a t-shirt, or other article, in place while manipulating the platen or screens. The adhesive wears out over time, as more and more items are stuck to and unstuck from the platen, so you may need to replace it from time to time.
